British Columbia, Canada, have invented a certain new and usefulImprovement in OverheadTrack Lines, of which the followingis aspecification.

This invention relates to an overhead wire rope transportation system,and -particu-.

larly comprises a means for laterally traverse ingthe outer end of theoverhead track line to enable a wider area to be included withi itsrange for transportation. I

outer end of the track line to a frame which is movable 'along ananchoring line or lines between two spar poles WlllCllfiIG laterallyspaced apart approximate the desired extent of lateral travel,--and isparticularly applicable tothe transportation system whereinv saidapplication having been filed on Sept tember 24, 1921, under Serial No.502,862.

The invention is particularly described in the following specification,reference being made to the drawings by which it is accompanied, 1nwhich: n I p I F 1g. 1 1s a plan of the track lineshowin U theapplication of the improvement;

Fig. 2 is a plan of the anchorage frame of. the outer end ofthetraclrline in which is the mechanism by which the frame itselfis laterallytraversed alongthe anchoring. line. Fig. 3 isa sectional plan of thesame, and Fig. at is a sectional-elevation on the line l4 in Figs. 2 and3. i

In these drawings 2representsthe'loca tion of the donkey engine and3 thespar pole adjacent the same. Parallel lines a and 5 of the track ropepass from separatedrums on the donkey engine over sheaves on thesparpole 3 at the required ,hei 'ht of the track and around a sheave 6rotatably mounted at :the outer limits of the track in a plate frame 7which .is carried on two transverse lines 11 between the outer. sparpoles 12 and 13, the connection of the. frame 7 to the supportinglines11 being such as will enable the frame to be traversed in a man ner tobedescribed between the spar'poles per and lower ovnnnnan raser: LINE.

. 12 land 13 and will be retained at any desired position between them.

This result is attained by having two reels 8 and 9 rotatably mountedbetween the upplates of the frame 7 with a third reellO of smallerdiameter between themi These reels are grooved to receive the ropesll-which are passed around, preferably in the following manner.

' (hie of the ropes 11 passes from one spar pole around the inner sideof the reel 8, around the outer side of the intermediate reel 10 andaround the reel 9'to encircle it,

' then around the inner side of the interme- This result is. attained bysupporting the from the inner, side of 8 to 9, around 9,

around the inner side of '10, around 8, around the outer side of 10, andaround the inner side of 9 to the other spar pole 13. This reversecoiling is that the tension of one rope will counteract that of theother in the pressure imposed on the bearings of the roller.

The friction of these ropes oppositely passedaround the reels 8, 9 and10 will effectively hold the frame 7 with the anchoring sheave 6 of theouter end ofthe track in an desired position on the ropes 11 between thespar poles 12 and 13.

It remains to describe how the reels8, 9 and 10 are rotated to effectmovement of the frame 7 on the anchoring lines.

- mountedin bearings secured between the upper and lower plates of theframe 7.

On'this shaft 30 a sleeve 33 is mounted to be endwise movable on'theshaftand rotate "with it by a'driving feather secured in the shaft. Eachend of the sleeve is'provided witha ratchet toothed clutch engagement 31and 32, the teeth of whichare angled to engagea-nddrive in oppositedirections, gear wheels 27, 29 freely rotatable on the same shaft. Theteeth of these gear wheels 27' and 29 mesh with those of gears 26 and 28secured 011 a parallel shaft 25, rotation of which is imparted toanother parallel shaft 22 through gears 24, 23. On tl e shaf 22 issecured a worm 21, the thread of which meshes with corresponding teethin a worm wheel 20 secured on an upright shaft 19rota'table in the frame7. To the upper end of this shaft 19 is secured a pinion 18, the teethof which mesh with those of a spur wheel 1'? secured on the upper end ofthe shaft on which the middle reel 10 is secured.

On the same shaft as this reel 10 is a gear wheel 16, the teeth: ofwhich mesh with those of wheels 14 and 15 secured on the adjacentreels'i'zand 9, the pitch circles of which gears 14, 15 and 16 are inthe same ratio as the diameters of the rope in the grooves of the reels.

Endwise movement of the track ropes 4 and 5 in relation to one another,which endwise movement is a characteristic of applicants system of wirerope transportation, thus rotates the sheave 6 around which the trackrope passes, and that rotational movement is imparted through the bevelgears 35, 34 to rotate the shaft 30 and may be applied to rotate theshafts 25 and 22 and through them the connected gearing to rotate thereels 8, 9 and 10 to traverse the frame 7 on the anchoring ropes 11.

The sleeve 33 is moved endwise to one side or the other to bring eitherclutch 31 or 32 into engagement to drive the gear train, by aforkedlever 37 secured on a vertically disposed rocking shaft 38, the fork ofwhich leverengages pins 39 projecting from segmcnts which fit a groovein the seeve On the upper end of this shaft 38' is secured a rocking arm40, the free end of which is apertured to move freely on a pin 41secured in the upwardly turned ends of a T projection 42 of an arm 43freely mounted on the shaft 38 and springs 44 are introduced betweeneach upwardly turned end and the arm 40, by which spring resistance thearm 40 is yieldingly moved with the arm 43. The outer end of this arm43' is connected at 45 by a rod 46 to a crank pin 47 secured in a disc48 mounted free on a stud 49 secured to andprojecting from the frame 7.

F our pins 50 are secured at an equal distance apart and at equal radiioutside the circle of movement of the crank pin 47 in the disc 48'.These pins 50 are designed to be engaged by a hook pawl 51 pivoted to abar 52 slida'bly mounted in the frame 7 to move endwise. This hook pawlis held in light engagement with. the pins 50 by a spring 53 The bar 52is held to project its end 54 beyondthe end of the frame 7 by a spring55', in which position the end 54 will be engaged by the transportationcarriage when it reaches the outer limit of its movement on the track 4,5 and will be pressed inward, in

which movement the crank disc 48 with its pin 47 will be rotated by thehook pawl 51 through a quarter of a revolution.

lV hen the crank pin 47 is at either limit of its throw, one or other ofthe clutch engagements 31 or is in action to traverse the carriage '7,but rotation of the crank disc through a quarter revolution from eitherof these limits will place the sleeve 33 in the neutral position, whenit will run free on the shaft 80 and the frame 7 with its track linesheave 6 is stationary on the anchoring lines 11; but if thetransportation carriage is allowed to reach the limit of its travel onthe track rope it will engage the end 54 of the bar 52 and move itinward to move the crank disc through a quarter revolution, whichmovement will either move the sleeve to throw it into engagement, if itis in neutral, or will release it from such engagement into neutral.

When the sleeve 33 is moved to bring either end'into clutchingengagement to move the frame 7 to or from either spar pole 12 or 13, itmay be allowed to remain there, and the frame '7 will be graduallytraversed in the manner described during endwise movement of the trackropes 4 and 5. If it is not desired to traverse the outer end of thetrack line the transportation carriage may be run to the end of thetrack lines, and the clutch sleeve 83 will be thrown into the neutralposition. v

The ratchet form of the teeth 31 and 32 and the spring connectionbetween the arm 43 and the arm 40 will enable engagement to be retainedwhether the track ropes are endwise moved one way or the other: Moved inone direction they will effect the traversing drive, while in theopposite direction the clutch teeth will pass over one another withouteffecting movement of the traversing gear.

A resilient brake 56 is applied to the edge of the crank disc 48 to holdit against any tendency to move back from the position to which it hasbeen set by the pawl 51.

I do not desire to be confined to the particular manner here describedand illustrated of effecting the traversing of the carriage on theanchoring lines 11', nor to the particular manner of throwing thistraversing mechanism into and out of action, as I regard the essentialfeature of the invention to be the means by which the outer end of anoverhead track line may be laterally traversed within a desired limitingwidth, and the means whereby that traversing movement may be effected byendwise movement of the track line.

Having now particularly described my invention, I hereby declare thatwhat I; claim as new and desire to be protected in by Letters Patent,is:
